3/4 full light when empty

[Guns338]

I have had the 3/4 full light when empty on, when I bought this Reflection used last august.
I flush our tanks every month or so using the onboard flush system, but always had the 3/4 full light.
Well today I decide to flush as usual but forgot about it for about an hour.
The flush ran for about an hour .... but no more 3/4 full light !!!!!

Thought I would share because I have seen several with this problem

Sounds like you had something stuck on the sensor. My brother-in-law suggested that we put Dawn detergent in the black water tank before use. It helps keep the oils broken up in there.

I've had good luck fixing that by, like you say, an extended soak and I have had good results from Simple Green. I still have my eye out for something like a hose end sprayer that would hook to the tank sprayer but has a soap dispenser like a car wash wand.
